The primary goal of this thesis is to develop a prototype device that can be used to demonstrate some key and fundamental concepts related to the disciplines of computer and electrical engineering to freshman engineering students. This objective is achieved through the development of a heart rate monitor that primarily consists of a sensor module for heart beat detection and a Microchip PIC-microcontroller based development board for heart rate calculation. The central element of the sensor module is an optical detection system that consists of a light-emitting diode and photodiode setup to detect heart beat from a measurement site with strong pulse like a fingertip. The obtained heart beat signal is then passed through multiple amplification and filtering stages to obtain a clean and strong heart beat signal. Using this optical sensor module implemented on a printed circuit board (PCB) we can demonstrate several concepts related to electrical engineering such as: basic electronics, semiconductor devices, analog circuit design, optical electronics, PCB design, etc. The voltage signal obtained from the sensor module is sent to a Microchip Explorer 16 development board for further signal processing and heart rate calculation. The development board contains a 16-bit PIC microcontroller with a built in 10-bit analog-to-digital converter that is used to digitize the analog voltage signal and calculate heart rate as beats per minute using a heart rate calculation algorithm. The calculated heart rate is finally displayed on an alphanumeric liquid-crystal display display that is included on the development board. This module of the prototype heart rate monitoring system is designed to be interactive and provide user-control to the heart rate calculation process while demonstrating some concepts related to computer engineering such as: microcontrollers, embedded systems, software development, hardware/software co-design, etc. The heart rate monitor developed in this research work has thus been designed to present a prototype device that can be used to demonstrate several key concepts related to computer and electrical engineering and this thesis document contains design and implementation details related to the development of this device.
